Retrieve All Files Present inside a Directory & Sub Directory Using C#.Net

This article will show you how you can retrieve all the files present inside the parent directory and inside the sub directory using c#.Net in a list collection.

Some of my previous articles are as follows: Short GridView Data From Header Using C#.Net In Asp.Net, Export GridView Or Table Data Into PDF By C#.Net In Asp.Net Using jQuery, Enable and Disable ADO.NET and OLEDB Connection Pooling In .Net, Group CheckBox In C# WinForm, Read Outlook Email Subject Using c#, Read Outlook Inbox Mail And Email Count Of Inbox Using C#.Net, How To Read XML File In DataSet And Display in DataGridview Using C#.Net.

So for this article first we will create a new console application and add the below code into the main function.

using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {             List<string> fileCollection = new List<string>();             string directoryPath = @"-----------------";             fileCollection = Directory.GetFiles(directoryPath, "*", SearchOption.AllDirectories).ToList();             Console.WriteLine("------File Read Start--------\n");             foreach (string item in fileCollection)             {                 Console.WriteLine(item + ", ");             }             Console.WriteLine("------File Read End--------\n");             Console.ReadLine();         }     } }

In above code I have specified he path of the folder to read all the files. Now we have done run the application to check the output.
